In the tabulation shown in Fig. 4, " title " and " album name " be described as be at all the lace of memory block information among file A and the B.
Fig. 5 illustrates before the format conversion file A (Fig. 2) and the format conversion example of file B afterwards.
The top of Fig. 5 illustrates the file A before the format conversion.When file A being offered form A analyzer 13 shown in Figure 1, form A analyzer 13 Study document A also extract lace information " title ", " the album name " and " 123 " that is stored among the frame #1-#3.
Form A analyzer 13 offers storer 15 or expansion area storer 16 based on the tabulation (Fig. 4) in the list memory 14 that is stored in Fig. 1 with lace information " title ", " the album name " and " 123 " that extracts.
For example, when the lace information of extracting was " title " and " album name ", form A analyzer 13 offered storer 15 with lace information " title " and " album name ", because " title " and " albumname " lists among Fig. 4.
When the lace information of extracting was " 123 ", form A analyzer 13 was rebuild lace information " 123 " based on form A, because lace information " 123 " is not listed in Fig. 4.Specifically, form A analyzer 13 storage titles and the major part that constitutes with frame #3 (" TXXX OMG TENTM 123 ") wherein are stored in lace information " 123 " in the expansion area storer 16 as the lace information " 123 " of rebuilding.
The lower part of Fig. 5 illustrates the file B that the form by the file A shown in the top of transition diagram 5 obtains.
In the file B shown in the lower part of Fig. 5, the district of source document B shown in Figure 3 is expanded.That is, begin label＜ETC at XML〉＜ID3 and XM end-tag＜/ID3＜/ETC between be provided with an expansion area.
As described in reference Fig. 5, lace information " title " and " album name " offered the storer 15 shown in Fig. 1 and after format conversion, the lace information " title " of file A and lace information " albumname " be stored in XML respectively begin label＜XML〉＜title and XML end-tag＜/title＜/TRACK between expansion area and the XML of file B begin label＜ALBUM＜title and XML end-tag＜/title＜/ALBUM between the expansion area of file B.
In addition, as described in the top of reference Fig. 5, with title (ID3 title) with use the lace information " 123 " of the reconstruction that the frame 3# (TXXX OMG TENTM 123) of the major part that provides from file A analyzer 13 constitutes to offer expansion area storer 16.Therefore, the lace information " 123 " of reconstruction is stored in XML as it is and begins label＜ETC〉＜ID3 and XM end-tag＜/ID3＜/ETC between the expansion area of file B in.
Fig. 6 illustrates the process flow diagram that file A is converted to first conversion process of file B with converter shown in Figure 11.First conversion process begins when file A being offered the form A analyzer 13 of converter 1.
In step S11, expansion 12 reads source document B (Fig. 3) from source document B storer 11, and expansion source document B also provides it to storer 15.
Then, in step S12, form A analyzer 13 Study document A also provide lace information.In addition, when in step S12, having extracted a plurality of lace information, to the processing of the step S13-S16 of each lace information and executing back.
In step S13, whether form A analyzer 13 reads the lace information of being extracted form (Fig. 4) and the determining step S12 from list memory 14 and is stored in the tabulation.That is, whether the form A analyzer 13 lace information of determining to be not used in the district of the lace information among the storage file B according to tabulation is stored in the district among the file A.
When determining that in step S13 the lace information stores is in tabulation, that is, when all being provided with in file A and file B when being used to store the district of lace information, form A analyzer 13 offers storer 15 and process with lace information and skips S14 and enter step S15.
For example, when the lace information of being extracted among the step S12 was " title ", " title " offered storer 15 with lace information, switched to step S15 because listed lace information " title " in the form of Fig. 4 and handled skips steps S14.
On the other hand, when in step S13, determining that lace information is not stored in the tabulation, that is, when the lace information that does not have the district in file B is stored in the Qu Zhongshi of file A, form A analyzer 13 is rebuild lace information and is provided it to expansion area storer 16 in step S14.
For example, when the lace information of being extracted among the step S12 is " 123 ", form A analyzer 13 is rebuild lace information " 123 " in step S14, because lace information " 123 " is not described in the tabulation of Fig. 4 and will constitutes title and be that the lace information " 123 " of reconstruction of major part of having stored the frame #3 of lace information " 123 " offers expansion area storer 16 and handles and enters step S15.
Then, in step S15, the lace information stores that storer 15 will be in step 13 provides from form A analyzer 13 the source document B (Fig. 3) that provides from expansion 12 at step S11 be arranged to store the district of this lace information, and this lace information is offered expansion area storer 16.
For example, when when form A analyzer 13 provides lace information " title ", storer 15 is stored in XML with this lace information " title " and begins label＜TRACK〉＜title and XML end-tag＜/title＜/TRACK between the district of source document B (Fig. 3) in and provide it to expansion area storer 16.
Then, in step S16, in the expansion area of the source document B that the lace information stores of the reconstruction that expansion area storer 16 will be in step S14 provides from form A analyzer 13 is provided among step S15.
For example, during the lace information " 123 " of the reconstruction that constitutes as the frame #3 that provides from form A analyzer 13 with title and major part, expansion area storer 16 is stored in the lace information " 123 " of rebuilding that XML begins label＜ETC among Fig. 5 same as before〉＜ID3 and XM end-tag＜/ID3＜/ETC between the expansion area of source document B in.
As mentioned above, the district of source document B and the lace information " 123 " that will not have to be stored in a file A in the district among the file B are stored in the expansion area in converter 1 expander graphs 3.Therefore, lose among the file B of lace information " 123 " after conversion that can prevent to be comprised among the file A of unconverted.Therefore, even lace information comprises important information, the form that converter 1 also can convert file and needn't emit the risk that needs loss of learning.
In addition, only when being stored among the file A, expansion 12 could be expanded the district of source document B in lace information (not providing storage its district among the file B).Whether form A analyzer 13 Study document A are stored among the file A with the lace information that does not have in the tabulation of determining list memory 14 to describe in the case.When the lace information stores that does not have in the tabulation of form A analyzer 13 decision list memories 14 to describe is in file A, form A analyzer 13 will instruct the control signal of expansion to offer expansion 12.In response to this control signal, the district of expansion 12 expansion source document B.
Fig. 7 illustrates the block scheme of an example of structure that the file B that is used for being changed by converter shown in Figure 1 converts the converter 31 of file A to.
Converter 31 shown in Fig. 7 is made of source document A storer 41, form B analyzer 42, storer 43, form A analyzer 44 and expansion area storer 45.
Source document A storer 41 is stored the file (hereinafter referred to as " source document A ") of the form A of thing.
To offer form B analyzer 42 by the file B (Fig. 5) of 1 conversion of the converter shown in Fig. 1.Form B analyzer 42 Study document B provide the lace information in the district in addition, expansion area that is stored in file B and provide it to storer 43.In addition, form B analyzer 42 provides the lace information of the reconstruction in the expansion area that is stored in file B and will offer form A analyzer 44 altogether.
Storer 43 reads source document A from source document A storer 41, will be in the district of source document A from the lace information stores of form B analyzer 42, and this district is configured to store the district of lace information, and provides it to expansion area storer 45.
Form A analyzer 44 is analyzed the lace information of the reconstruction of B analyzer 42 from form and is extracted this lace information.Because the lace information of rebuilding is rebuild by form A, form A analyzer 44 can be identical with the form A analyzer 13 shown in Fig. 1.Therefore, there is no need to develop the new analyzer of analyzing stored that be used for, thereby can reduce cost in the lace information of the reconstruction of the expansion area of file B.
In addition, form A analyzer 44 offers expansion area storer 45 with the lace information of extracting.Expansion area storer 45 will be used for storing exporting as file A from the district of the source document A of storer 43 and with it of this lace information from the lace information stores of form A analyzer 44.
Fig. 8 illustrates file B and the format conversion file A afterwards before the format conversion.
The top of Fig. 8 illustrates the preceding file B of format conversion and identical with the lower part of Fig. 5. are when the file B shown in the top of Fig. 8 is divided offers form B analyzer 42, and form B analyzer 42 Study document B are stored in except XML with extraction and begin label＜ETC〉＜ID3 and XM end-tag＜/ID3＜/ETC between the expansion area XML begin label＜TRACK＜title and XML end-tag＜/title＜/TRACK between the district in lace information " title " and be stored in XML and begin label＜ALBUM＜title and XML end-tag＜/title＜/ALBUM between the district in lace information " album name ". Then, form B analyzer 42 offers storer 43 with lace information " title " and " the album name " that extracts.
In addition, form B analyzer 42 extracts and is stored in XML by title (ID3HEADER) and storage and begins label＜ETC〉＜ID3 and XM end-tag＜/ID3＜/ETC between the expansion area in the lace information " 123 " that constituted of the major part (TXXX OMG TENTM " 123 ") of lace information " 123 " and the lace information " 123 " of reconstruction offered form A analyzer 44.The lace information " 123 " that form A analyzer 44 analysis is rebuild is extracted lace information " 123 " and is provided it to expansion area storer 45 from the frame #3 of major part.
The lower part of Fig. 8 illustrates the file A of form after conversion of the file B shown in the top of Fig. 8.
With regard to the top of Fig. 8, lace information " title " and " album name " are provided for storer 43.Therefore, shown in the lower part of Fig. 8, lace information " title " be stored in be arranged to store lace information " title " in the district of the frame #1 of the file A of format conversion and lace information " album name " be stored in be arranged to store lace information " album name " in the district of the frame #2 of the file A of format conversion.
Because be provided for the expansion area storer 45 on the top of the described Fig. 8 of being called from the lace information " 123 " of file A analyzer 44, shown in the lower part of Fig. 8, lace information " 123 " be stored in be arranged to store lace information " 123 " in the district of the frame #3 of format conversion file A.
Fig. 9 is that the converter 31 that illustrates with Fig. 7 will be converted to the process flow diagram of second conversion process of file A by the file B that converter shown in Figure 1 is changed.For example when file B was provided for the form B analyzer 42 of converter 31, second conversion process began.
In step S31, form B analyzer 42 Study document B.In addition, the district of form B analyzer 42 beyond from the expansion area extracts lace information and this lace information offered storer 43.Form B analyzer 42 further extracts the lace information of rebuilding and provides it to form A analyzer 44 from the expansion area.
In step S32, storer 43 reads source document A from source document A storer 41, will be arranged to store the district of source document A of this lace information and provides it to expansion area storer 45 in the lace information stores that step S31 provides from form B analyzer 42.
For example, when when form B analyzer 42 provides lace information " title ", storer 43 is stored in this lace information " title " among the frame #1 of the source document A that is arranged to store this lace information " title " and provides it to expansion area storer 45.
In step S33, form A analyzer 44 the lace information of the reconstruction that provides from form B analyzer 42 is provided in step S31 and is extracted lace information.
Specifically, when the lace information " 123 " of the reconstruction that major part constituted that constitutes with title (ID3 HEADER) with the frame #3 (TXXX OMG TENTM " 123 ") of storage lace information " 123 " was provided from form B analyzer 42, form A analyzer 44 was analyzed the lace information " 123 " of rebuilding and is extracted lace information " 123 " from the frame #3 of major part.
In step S34, expansion area storer 45 will provide from storer 43 among step S32 in the lace information stores that step S33 provides from form A analyzer 44 is arranged to store the district of source document A of this lace information and exports it as file A.
For example, when when form A analyzer 44 provides lace information " 123 ", expansion area storer 45 is stored in lace information " 123 " among the frame #3 of the source document A that is arranged to store this lace information " 123 ", and it is exported as file A.
As mentioned above, in converter 31, form B analyzer 42 extracts the lace information in the district in addition, expansion area that is stored in file B and is stored in the lace information of the reconstruction in the expansion area, and the reconstruction lace information extraction lace information of form A analyzer 44 from extracting.Storer 43 and expansion area storer 45 are with in the district and the expansion area of the file B among the source document A of lace information stores beyond the expansion area.Therefore, can prevent from before its format conversion, to be included among the file A of lace information after conversion among the file B and lose.
As a result, when the file B that will convert from file A in converter 1 is converted into file A, the file A in converter 1 before the conversion and consistent with each other by the file A of converter 31 conversions.
In addition, in the above description, the lace information of file A is ID3v2, and the form of the lace information of file B is based on XML.Yet as long as be useful on the district of stores binary data in form, any form can be used as the form of lace information.
